Add note for .NET tool dependencies (#10020)

[abdulrahmanhossam]

Fixes #10020

Description
Updated the DependencySetsViewModel and DisplayPackageViewModelFactory to pass the IsDotnetTool flag.
Modified _PackageDependencies.cshtml to display a note with a link to issue #10020 when a package is a .NET Tool and has no explicit dependencies in its nuspec.

Expected Behavior
Instead of showing "This package has no dependencies.", .NET tools will now show: ".NET tools have dependencies embedded in the package." along with a link to gather upvotes for improving the experience.

Hi @joelverhagen, thanks for the assignment! 🚀

I've updated the base branch to dev as requested.

Here is a mockup screenshot of how the UI will look with the proposed changes:

I'm totally open to any feedback on the wording or implementation from the team! Let me know what you think.

Thank you for the contribution @abdulrahmanhossam! 🎉

One small suggestion on the wording, instead of "See this issue to vote and improve this experience", how about:

.NET tools have dependencies embedded in the package. Join the discussion on improving this experience.

This sets the right expectation for users clicking through.

Makes sense (still funny that I'm the only one who has upvoted the issue in two years 😅)

Thanks for the feedback, @pranathibora14! That wording definitely makes more sense.

I've just pushed a commit to update the message as suggested. Let me know if there's anything else needed!
